That would work if you don't mind the taste of the nutrients....lol

Really, you do need to flush. Advanced nutrients have a very good flusher called Final Phase. It's expensive but it does work, I switched from clearex to flora kleen and now use final phase. I do notice a big taste difference between all the flushers and final phase works the best. Regular Ph water only does not get enough of the nutrients from inside the plant and takes three times as long to flush completely. IMO
